Abstract: A grinder for a coffee machine includes a first grinding disc disposed in a housing. A drive moves the first grinding disc about a rotational axis. A second grinding disc is disposed in the housing. There is a threaded part in which the second grinding disc is attached. The threaded part is screwable into the housing. A drive wheel is disposed coaxially with respect to the threaded part and rotates the threaded part with respect to the housing. A grinding gap between the two grinding discs is thereby able to be set. A setting wheel co-operates with the drive wheel, the setting wheel being attached to the housing. A supply opening is disposed in the housing for supply of coffee beans to be ground. A path guide opening guides away the coffee ground between the two grinding discs. A holder is adjustably attached to the housing and is fixable in any position.

Abstract: Inserted into the housing (2) of a grinder for a coffee machine is a first grinding disc (6), which, via drive means (3), is drivable about a rotational axis. A second grinding disc (9) is attached in a screw-in part (7) which is screwable into the housing and is rotatable with respect to the housing (2) by adjusting means (15), (16). By rotating the screw-in part, the grinding gap between the two grinding discs (6), (9) can be set. The adjusting means comprise a setting wheel (16) arranged on a holder (17) which is attached to the housing (2) and which can be adjusted and fixed in any position with respect to the housing (2). This setting wheel co-operates with the drive wheel (15) attached to the screw-in part (7). The setting wheel (16) which is attached to the holder (17) can thereby engage in the drive wheel (15) in any desired position with respect to the housing, whereby the thus equipped standard grinder can be inserted into different types of coffee machines.

Abstract: An apparatus for removing copies and/or documents from a machine has a catch and removal tray (2) which can be extended telescopically out of the machine (1). The catch and removal tray (2) consists of a fixed section (3) inside the machine (1) and a movable section (4) which can be drawn out of the machine (1). The fixed section of the tray (3) acts as a catch tray for documents processed by the machine (1) and has a drive mechanism (6, 7, 19) which drives a sliding panel (5) which extends downwards into the fixed section of the tray (3) and which pushes the stack of documents (8) from the fixed section of the tray (3) into the extended movable section of the tray (4). The fixed section of the tray (3) has a photoelectric cell (20) which activates the sliding panel (5) when the stack of documents reaches the maximum height.
